Definitions

  • the invention relates to a light fixture for illuminating building surfaces or parts thereof according to the characterizing clause of claim 1 .
  • the know light fixture has an aluminum reflector that is generally parabolic.
  • the reflector is formed from an aluminum disk that is rotated and pressed against a pin (male die part). It has after the shaping 10 process an inner surface that conforms to the die and that is formed by the male die part.
  • the known reflector has a plurality of segments that each have a generally planar face. Both seen angularly as well as from an edge of the reflector toward its apex the rows of adjacent segments together form a polygonal course.
  • the invention attains this object with the feature of claim 1 , in particular with those of the characterizing clause, and is thus characterized in that the segments each have an inwardly directed arcuate surface.
  • the principle of the invention is generally that instead of using segments with generally planar faces that ensure a reflection of the light from the lamp in the standard manner, now arcuate surfaces are provided that fan out the individual light elements or ray bundles and thus make them more uniform. In this manner it is possible to reduce the light density on the reflector surface by spreading it over a number of segments. In addition it is possible to minimize stray portions since the curved, in particular generally spherical arcuate segments, can be particularly precisely tuned in advance and correspondingly exactly formed.
  • the light fixture according to the invention makes possible a predetermined reflecting characteristic of the light fixture by the selection of the curvature radii of the surfaces of the segments.
  • each segments is preferably curved in two directions and thus has a first and a second radius of curvature.
  • the reflective characteristic of the fixture can be influenced strongly. Smaller radii lead to a greater fanning-out of the light and are therefore preferred when the fixture is a floodlight so that a large surface of a building can be illuminated. Larger curvature radii produce parallel light beams and are thus used when the fixture is employed as a spotlight and only illuminates a fairly restricted region. e.g. a circular area, of a building surface.
  • the building surface or portion thereof is in particular a building wall, a building roof, or a building floor, and for outside fixtures of course paths or streets can be illuminated.
  • the fixture according to the invention is stationary, preferably mounted on a building surface or part thereof, but can also be provided on a pole or the like.
  • the building surface or portion thereof according to the present application can also be an object on a building surface, e.g. artwork.
  • the fixture according to the invention for illuminating building surfaces or portions thereof can also illuminate an object, which is in particular of interest when the fixture is used as a spotlight.
  • the structured arrangement of the segments according to the introductory clause of claim 1 includes such segments that are arrayed according to a particular pattern or raster relative to one another.
  • the segments can thus be set in any desired raster.
  • Such a raster is necessary in any case in order to achieve the desired reflecting characteristic of the fixture.
  • an array is used wherein the segments are set in generally annular arrays extending angularly, the number of segments in each annular array not changing and in fact being constant as the distance of the annular array from the apex changes.
  • a lamp is provided or mountable at a focal point of the reflector. This makes it possible to accurately control the reflective characteristic of the fixture.
  • Such positioning of the lamp at the focal point is particularly advantageous when the reflector is generally parabolic.
  • the reflector is generally parabolic.
  • other cup shapes for the reflector are possible.
  • several lamps can also be mounted inside the reflector. It is mainly important that the light sources be at least near the focal point.
  • the reflector is generally rotation symmetrical. This facilitates a particularly simple shape and manufacture of the reflector as well as a particularly homogeneous illumination of the building surface.
  • the surface is double curved.
  • the surface has a first curvature with a first radius and a second curvature with a second radius.
  • the surface of each segment is thus generally part-spherical. This is not necessarily a part of a spherical surface, but a surface curved in three dimensions that is curved along two different radii of curvature.
  • a spherically curved surface is only used in the particular circumstance when the first radius and the second radius are the same. This case is not in the scope of the invention.
  • the reflecting characteristic of the fixture can be determined very accurately.
  • the building surface or part thereof can be carefully and homogeneously illuminated.
  • the first and the second radii are different depending on a spacing of the segment from an apex of the reflector. This makes possible a particularly exact predetermining of the reflective characteristic of the fixture.
  • every two segments are immediately adjacent each other.
  • the entire inner surface of the reflector is formed by the surfaces of the individual segments. This reduces the light density on the reflector surfaces and minimizes stray light.
  • the segments are arranged linearly relative to the curved inner face of the reflector.
  • the segments are thus arrayed along a straight line looking into the interior parallel to the rotation axis of the reflector or along its central longitudinal axis.
  • the segments since the inside of the reflector is itself curved, extend along a curved path that follows the inner shape of the reflector. This curved path is the shortest distance between the apex of the reflector and the edge of the reflector.
  • the size of the segments increases from an apex of the reflector toward a light-outlet opening of the reflector. This makes it possible to completely fill the inside of the reflector with segments.
  • the entire inner face of the reflector is covered with segments.
  • the segments thus cover the inside of the reflector from its free edge up to its apex, thus up to the opening through which the lamp or a socket for the lamp is inserted, furthermore preferably the number of segments angularly is independent of the spacing of the segments from the apex of the reflector and is constant. This produces a particularly homogeneous illumination of the building surface or part thereof.
  • an edge of the reflector has a rim. This makes it particularly simple to provide mounting formations.
  • the invention further relates to a light fixture for illuminating building surfaces or parts thereof according to the introductory clause of claim 24 .
  • This invention is also aimed at the already described light fixtures of applicant.
  • the object of this invention is so to improve the known light fixtures that they are of simpler construction.
  • the invention attains this object with the features of claim 24 , in particular with those of its characterizing clause, and is thus characterized in that the segments each have an inwardly directed arcuate surface, the reflector having a spacing between an apex and a free edge and a light-outlet opening, in particular a generally circular light-outlet opening, with a first diameter, the reflector being interchangeable with a second reflector with the same spacing and the same diameter but having segments that are differently curved from the first reflector.
  • the principle of this invention is mainly that a first reflector and a second reflector have the same outside dimensions or measurements, also the same spacings and diameter.
  • the first and the second reflectors are thus interchangeable with each other.
  • both the first and the second reflector can thus be used in the same fixture, advantageously with the same fasteners.
  • the two reflectors have differently curved surfaces that are different with respect to their radii fo curvature.
  • the first reflector has a plurality of segments that have large radii and the second reflector has a plurality of segments that have smaller radii.
  • the first reflector imparts a first reflective characteristic to the fixture. e.g. that of a standard spotlight
  • the second reflector has a reflective characteristic different from that of the first reflective characteristic, that of a standard floodlight.
  • the principle according to the invention makes it possible to simplify the necessary expensive construction of different fixtures for different reflective characteristics. It is simply only necessary to make different reflector.
  • the fixtures can be completely identical with regard to the chamber for the reflector, the fixture housing, and the mounting elements for the reflector. Finally even the reflective characteristic of an already installed, that is site-mounted fixture, be changed by switching out the reflector as needed.
  • FIG. 1 is a schematic view from below according to view arrow I of FIG. 2 of a first reflector with a plurality of segments with arcuate surfaces;
  • FIG. 2 is the embodiment of FIG. 1 in partial section taken along line II—II of FIG. 1 ;
  • FIG. 3 is a second embodiment of a reflector according to the invention shown as in FIG. 1 ;
  • FIG. 4 is the embodiment of FIG. 3 shown as in FIG. 2 but along the section line IV—IV of FIG. 3 ;
  • FIG. 5 is an enlarged view of a detail of FIG. 4 as shown by rectangle V;
  • FIG. 6 is an enlarged sectional view of the embodiment of FIG. 4 generally along section line VI—VI of FIG. 4 .
  • the reflector is shown in general in the drawing at 10 , and similar parts or elements of the two different embodiments of FIGS. 1 and 2 on one hand and 3 to 6 on the other have the same references for simplicity's sake, partially with the addition of lower-case letters.
  • FIGS. 1 and 2 show a generally parabolically curved reflector 10 having an apex 11 and an edge 12 .
  • the axial distance between the apex 11 and the edge 12 that is the height or apex height of the reflector 10 is shown in FIG. 2 at h 1 .
  • the edge 12 of the reflector defines a generally circular light-outlet opening 20 of diameter d 1 . This corresponds thus to the inside diameter d 1 of the reflector 10 at its widest part.
  • the reflector 10 is spread outward and has a flange 13 .
  • this flange 13 as best shown in FIG. 2 there are two notches 14 a and 14 b that serve for mounting.
  • Unillustrated mounting elements e.g. screws, pass partly through these edge notches 14 a and 14 b to secure the reflector in an unillustrated housing of an also unillustrated light fixture.
  • the reflector 10 is thus fitted inside the light fixture.
  • an upper surface 30 of the flange 13 abuts a surface of the fixture housing so that the flange 13 and thus the entire reflector is fixed against this mounting surface.
  • a hole not shown in the drawing that is typically formed as an opening at a longitudinal central axis 1 of the reflector 10 at its apex 11 .
  • the opening is normally formed by stamping or cutting out of the apex 11 .
  • a lamp is inserted through this unillustrated opening so that the lamp 10 when mounted is in an interior 21 of the reflector 10 , preferably near a focal point 22 shown only in FIG. 2 .
  • the reflector 10 has on its inner face 27 a plurality of segments.
  • FIG. 1 shows the peripheral adjacent segments by way of example at 15 a , 15 b , 15 c , and 15 d , with eighty segments in an angular row forming an annular group.
  • the segments extend from the edge 12 of the reflector 10 up to the apex. As shown in FIG. 1 the segments are arrayed along straight lines 18 that are shown in the view of FIG. 1 to extend from the apex of the reflector 10 to its edge 12 . This forms a spider-web structure or raster.
  • segments 15 a , 16 a , 17 a are shown that extend along the line 18 a .
  • segments extend along this line 18 a from the apex 11 of the reflector 10 to its edge 12 . It is important that the lines 18 and 18 a are only straight as seen in FIG. 1 .
  • the lines 18 and 18 a follow the parabolic shape of the reflector 10 which is shown in particular in FIG. 2 .
  • the line 18 thus extends in the shortest possible route from the edge of the reflector to the apex 11 .
  • FIG. 1 shows that the reflector 10 has a concentric array of circular groups of segments.
  • one group of eight segments forms immediately adjacent the edge 12 of the reflector a circular group 29 a of segments.
  • Further radial inward and closer to the apex 11 is a third circular group 29 c of segments.
  • Overall the number of segments along a straight line corresponds to twenty circular groups 29 of segments.
  • Each group of segments has eighty segments.
  • Each group 29 a , 29 b , 29 c of segments runs along a circular line 28 a , 28 b , 28 c . All the circular lines 28 , 28 a , 28 b 28 c are concentric circles.
  • the entire inner face 27 of the reflector 10 is covered with segments (e.g. 15 a , 15 b , 15 c , 16 a , 16 b , 16 c ).
  • the inner face of the reflector 10 is thus wholly comprised of the individual arcuate surfaces 31 a , 31 b , 31 c , 31 d of the individual segments. Each segment has its own surface.
  • FIGS. 3 and 4 show a further embodiment of the reflector according to the invention, which has the same number of segments. In addition there are eighty segments counting angularly and twenty along a line 18 .
  • the reflector 10 according to FIGS. 3 and 4 has a height h 2 that is identical to the height h 1 of the first embodiment. Even the inside diameter d 2 of the light-outlet opening 20 of the reflector 10 is identical to the inside diameter d 1 of the first embodiment. Finally an outside diameter a 2 of the reflector 10 according to FIGS. 3 and 4 is identical to the outside diameter a 1 of the first embodiment. The same is true for the mounting notches 14 a and 14 b.
  • FIG. 5 shows an enlarged detail from FIG. 4 from somewhere between the edge 12 and the apex 11 .
  • FIG. 5 shows by way of example in sectional view segments 23 a , 24 a , 25 a , and 26 a .
  • FIG. 5 shows a section through the circular groups 29 i , 29 j , 29 k , 29 l , 29 m , 29 n , and 29 o of segments.
  • FIG. 5 is a generally vertical section
  • FIG. 6 is a horizontal section through the reflector 10 .
  • the circular group 29 e of segments is shown.
  • the circular groups 29 f , 29 g , 29 h , and 29 i of segments as well as further circular groups.
  • each segment has a generally trapezoidal shape. While the two opposite sides 33 a and 33 b that angularly delimit the segment 33 are of substantially the same length, the radially inner side 34 toward the apex 11 of the segment 32 is shorter than the side 35 of this segment 32 closer to the edge 12 , so as to produce the trapezoidal shape. It is notable that this trapezoidal shape is only seen in a frontal view of the segment 32 . The actual trapezoidal shape is produced when a surface 36 of the segment 32 is projected on a plane. Even seen this way the trapezoidal shape is only approximate since, according to how the surface 36 of the segment 32 is curved the projected surface will not necessarily have straight edges.
  • FIG. 5 shows the radius r 1 of curvature while on the other hand
  • FIG. 6 shows the second radius r 2 of curvature.
  • FIG. 6 shows in the group 29 e of segments shown in section a curvature radius r 2 .
  • the surfaces 31 a , 31 b , 31 c , and 31 d of the respective segments 19 a , 19 b , 19 c , and 19 d have a corresponding curvature radius r 2 , but this is not shown.
  • Reference r 2 ′ shows that there is a second curvature radius r 2 that represents the curvature of the surface of a segment when the segment is sectioned longitudinally, that is generally perpendicular to the lines 18 delimiting the segment sides.
  • the curvature radius r 2 ′ of the surfaces 31 a , 31 b , 31 c , and 31 d of the segments 19 a , 19 b , 19 c , and 19 d is shown in FIG. 6 but this figure shows these segments 19 a , 19 b , 19 c , and 19 d in frontal view and not in section so that they are not clearly recognizable.
  • the second curvature radius r 2 of the group 29 e of segments is advantageously different from the curvature radius r 2 ′ of the group 29 g of segments 19 a , 19 b , 19 c , and 19 d.
  • This curvature radius r 2 defines a curvature of the respective surface 37 of a segment 38 and an unillustrated curvature axis that extends generally parallel to the longitudinal central axis 1 of the reflector 10 .
  • the segment 32 that is closer to the apex 11 of the reflector 10 than the last-discussed segment 38 has a curvature with the radius r 2 that corresponds to a curvature axis that defines a plane together with the longitudinal central axis 1 of the reflector, that is a section plane for the reflector along which the reflector is divided into two generally identical halves by a longitudinal section like that of FIG. 4 .
  • the family of curvature axes includes straight lines that intersect the central axis or rotation axis 1 of the reflector 10 and the intersection as in FIG. 2 lies above the apex 11 of the reflector 10 .
  • the radius r 2 of the group 29 i of segments can be different from that of the radius r 2 of the group 29 e of segments.
  • Each surface of each segment is also arcuate along a further radius r 1 . This curvature can be seen in FIG. 5 .
  • a surface 40 of the segment 26 a is formed with a radius r 1 having a schematically shown curvature axis 39 .
  • This curvature axis 39 is generally perpendicular to the longitudinal central axis 1 of the reflector 10 .
  • each segment of a group e.g. the group 291
  • the individual segments of a group, e.g. the group 291 thus have different curvature axes 39 , and the family of curvature axes 39 of a group 291 of segments all lie in the same plane.
  • the longitudinal axis 1 is perpendicular to this plane.
  • FIG. 5 shows how the segments 23 a , 24 a , 25 a , and 26 a each have a surface with a curvature radius r 1 .
  • the individual curvature radii r 1 of the different groups 29 j , 29 k , 29 l . etc. of segments are all different.
  • FIGS. 5 and 6 generally show that the first curvature radius r 1 and the second curvature radius r 2 vary depending on the spacing of the respective segments from the apex 11 of the reflector 10 , while within an annular group 29 of segments they are constant.
  • a first embodiment of a reflector 10 according to FIGS. 1 to 3 can have for example 1600 segments with each segment having a surface that is curved along two different radii r 1 and r 2 .
  • the second embodiment of a reflector 10 according to FIGS. 3 to 6 has the same number and arrangement of segments, but the individual segments have in contrast to the embodiment of FIGS. 1 and 2 differently curved surface surfaces of the segments with other radii r 1 and r 2 .
  • the reflecting characteristics of the fixture can be varied. Different reflecting characteristics of the fixtures are created simply by changing the radii r 1 and r 2 .
  • the mounting cutouts 14 a and 14 b are identical in the two different reflectors.
  • the same fixture housing and the same mounting means can use either the first embodiment of a reflector according to FIG. 1 or alternatively the second embodiment of a reflector of FIG. 3 without having to do any particular conversions.
  • the typical reflecting angle is between 5 and 15° whereas for a floodlight fixture the angle is 50 to 70°.
  • intermediate reflecting angles can be used, and the reflector according to the invention can also be set up for fine increments or degree distributions.
  • the fixed number of 1600 segments is of course arbitrary. It is perfectly possible that two interchangeable reflectors have the same height (h 1 and h 2 ), outer diameters (a 1 and a 2 ), and diameters (d 1 and d 2 ), but have different numbers of segments.
  • the reflector 10 is made preferably of pressed aluminum. To this end an aluminum disk of circular shape, is moved along a rotating pin so that the pin (male die part) deforms the aluminum disk. As shown in particular in the section of FIG. 5 , the inner face 27 of the reflector 10 is completely free of undercuts. The reflector 10 can therefore be taken from the male die part with no difficulty in a linear movement.
  • the use of pressed aluminum as the material for the reflector ensures that the inner surface 27 is reflective, so that particular treatments are not needed.
  • the reflector can be made for example of injection-molded plastic or glass provided with a reflective surface applied for example by vapor deposition.
